Grooved Crater Ejecta
This VIS image shows an unnamed crater located in Terra Sirenum. The surface of the ejecta contains radial grooves, visible on the thicker ejecta near the crater rim. The formation mechanism for the grooves is still unknown but several theories exist including basal surge flows and air pressure rock entrainment. Several gullies dissect the inner crater rim.
